What I want is a popup, that has a link, when I click the link, it should update the current tab.

So, I was thinking a script on the html page, using the script for tabs.

There are obstacles:
1 - the script code adds a listener. Can I add a listener to my link in the web page? I don't need a listener, I simply want to say, user clicked, you go and update the page.

2 - the script is diabled by security. I have enabled tabs in the manifest but this is beyond that.

I get:

Refused to execute inline event handler because it violates the following content security policy directive: script-src self blob filesystem chrome-extension-resource. Either the unsafe-inline keyword, a hash sha256.. or a nonce nonce- is required to enable inline execution.
